Abstract: Mesoporous silica with different morphologies was synthesized in a base medium. The effects of factors such as pH, reaction temperature, concentration of CTAB and EtOH on morphologies of mesoporous silica were studied by means of TEM and XRD. The silica particles with 30-50nm in diameter and well-ordered were synthesized.

Key words: silica, mesoporous particles, morphological control
